Opensource Alternative to Document360 or Archbee? [For Non-Technical Users]

I'm a huge advocate of open-source software.

I was looking for open-source (self-hosted) alternatives to Document360 or Archbee.

Has anyone come across something similar?

I've tried Docusaurus. It's great but a big no to non-tech people and the features are much less.

PS: If something like this is nonexistent, I'm gonna build this since I'm a developer.
